1 OneGeology-Europe: Data Harmonization across Europe Challenges and recommendations - Kristine Asch and 1G-E Workpackage 3 1

2 Talented little sister of the global OneGeology initiative Funded by EC DG Information Society and Media with 2,7 Million (total budget: 3,25 Million ) for 2 years 10 Work Packages 29 partners in 20 participating countries, Start: September

4 Project deliverables Interoperable on-shore geology spatial dataset with progress towards harmonisation Geological vocabulary and data specifications for Europe Use case studies Multilingual metadata for discovery View services Forerunner and guinea pig for the implementation of INSPIRE Directive 4

5 Main aims Building a Geological spatial data infrastructure for Europe That includes: making geological information of Europe available for everyone, at a 1 : 1 Million scale, web accessible, interoperable, with progress towards harmonisation 5

6 Interoperability and harmonisation Interoperability agreeing the data model/structure and the properties to describe its parts (what GeoSciML does) E.g. agreeing a data model will have the feature of GeologicUnit with properties of age and lithology Semantic harmonisation agreeing the use of the same definitions and classifications to describe a concept/term E.g. clay. The same concept can be labelled with several terms ( argilla in Italian, Ton in German), but needs to have the same definition, in this case: > 50% particles < 0,004 mm (Wentworth grade scale). Geometric harmonisation coping with mismatches at national boundaries 6

9 A Common Vocabulary OneGeology-Europe scientifc geological vocabulary reviewed and completed (February 2010) Essential base for semantic harmonisation across political boundaries Enables comparability of the information Basis for cross-boundary planning 532 review comments from project partners, CGMW and CGI 516 agreed defined terms and definitions on: Lithology (sedimentary, magmatic, metamorphic) geological age Genesis (environmental process, event) faults > 100 new terms and definitions fed into the global CGI vocabulary 9

10 Vocabulary Building Global CGI Vocabulary Extract European national and scientific requirements INSPIRE Geology data specifications DRAFT Review 1GE core Team Particularily European properties (e.g. orogenies) 1G-E Vocabulary 20 national Geol Surveys 10

11 WP 3 Portrayal Rules visualizing the content and its status of harmonisation 11

12 Differing geographical reference: Boundary country A Boundary country B Data gaps no content Definition of the political boundary 12

13 Differing level of detail Differing scales of the original source data Different levels of detail in the description of the geologic unit (here: age). 13

14 Different semantic description of the same geologic unit Boundary of Italy and Slovenia: differing determination of the dominant lithology. Cambrian Carboniferious Italy/France: same geologic unit age described Cambrian / Carboniferous respectively 14

15 Discontinuity of geologic units and structures Border between Belgium and Germany (near Aachen) a) Displacement of a geologic unit at the national border, b) Artificial termination of a geologic unit at the border. a) b) 15

16 Mismatch Matrix: Identification and classification of mismatches NE Germany/NW Poland 16

17 Challenges > 9000 Km political boundaries within 1G-E participants Hardly any country harmonises voluntarily its data with its neighbour s boundaries Distributed data: no central editing (as at Geol Map of Europe - IGME 5000) Agreement: 10 individual country representatives defining terms and definitions 20 national representatives reviewing The (English) project Language a neverending source for misunderstanding - > target scale 1/ Data delivered in 1/ , 1/ , 1/ , 1/ , 1/ , 1/ Communication between the geologists and informatics specialists 17

18 Geological harmonisation: Draft of a general workflow process Required: parties use same conceptual model and vocabulary Expert group Expert group Tools: Mismatch matrix Tools Mediator Neighbours 18

19 OG-E Harmonisation Workshop in Slovenia Sometimes unconventional measures could not be avoided. I will do anything, I will even HARMONIZE!!! AAAAARGH! 19

20 Summary and Conclusions Solid base vocabulary to describe the geology of Europe OneG-E data vocabulary improved the global CGI vocabulary The 1G-E/CGI vocabulary: base for the INSPIRE Geology code lists of lithology, Genetic environment, process, faults, age, Reviewed and agreed by 20+4 countries Harmonisation takes time: within 1G-E WP3 impossible to solve ALL harmonisation issues progress-towards-harmonisation report: guidance for future cross-border consistency and harmonisation A technical harmonisation tool would have helped considerably Astounding: complexity of the harmonisation issues, often further field work needed! Negotiation processes often needed 20
